PLYMOUTH MEETING, Pa., July 25, 2019 /PRNewswire/ -- Inovio Pharmaceuticals, Inc. (INO) today announced that positive results from the first-in-human trial of its vaccine against the Middle East Respiratory Syndrome Coronavirus (MERS) were published in The Lancet Infectious Diseases. This peer-reviewed article entitled, "Safety and immunogenicity of an anti-Middle East respiratory syndrome coronavirus DNA vaccine: A phase 1, open-label, single-arm, dose-escalation trial," highlights clinical results of Inovio's collaborative vaccine study of INO-4700 (also called GLS-5300) against MERS delivered with the CELLECTRA® efficacy-enhancing device.
Dr. J. Joseph Kim, Inovio President and CEO, said, "This latest publication underscores the potential for rapid deployment of Inovio's DNA vaccines. Impressively, INO-4700 was advanced into the clinic within nine months of vaccine candidate selection -- the first MERS vaccine in humans. Inovio is planning a Phase 2 MERS vaccine trial to be conducted in areas of the world where outbreaks have occurred, funded through our previously established collaboration with CEPI dependent on Phase 1b/2a data."
Inovio and GeneOne Life Science, Inc. (011000.KS) are co-developing INO-4700 in this 75-participant clinical trial conducted at the Walter Reed Army Institute of Research Clinical Trials Center (WRAIR) in Silver Spring, MD. Subjects vaccinated with INO-4700 displayed robust levels of MERS antigen-specific antibody and T cell responses at week 14 (two weeks post-third dose). These vaccine-generated immune responses to INO-4700 were durable as they were maintained through 60 weeks following dosing. Inovio's MERS DNA vaccine was well-tolerated and demonstrated overall high levels of antibody responses in 94% of subjects, while also generating broad-based T cell responses in 88% of study participants. Furthermore, INO-4700 administration generated antibody responses with similar potency compared to those of patients who were infected with MERS virus and subsequently recovered from the South Korea MERS outbreak. Even more interestingly, the vaccination generated more robust T cell responses than convalescent patients, suggesting the vaccine's ability to protect from reinfection from MERS virus.
MERS is a severe respiratory disease akin to the Severe Acute Respiratory Syndrome (SARS) and was first identified in Saudi Arabia in 2012. MERS has infected more than 2,400 people and killed nearly 35% of those infected. There are currently no licensed vaccines or specific treatments for MERS. MERS has been identified as a priority disease by the World Health Organization (WHO) and as a top target for vaccine development by the Coalition for Epidemic Preparedness Innovations (CEPI).
Dr. Kayvon Modjarrad, director of WRAIR's Emerging Infectious Diseases Branch, the principal investigator of the study and first author on the publication, said, "The world witnessed the emergence and devastation of SARS in 2002 and then MERS 10 years later. MERS hasn't gone away. And there's every indication that the family of viruses to which SARS and MERS belong, coronaviruses, are here to stay. U.S. military personnel are at particular risk for MERS, given the deployments to the Middle East and South Korea where the largest MERS outbreaks have occurred. This study is, therefore, an important advancement for the U.S. Army, the military community as a whole and the global stakeholders in the research and development of both MERS and corona virus countermeasures."
This study was funded by the U.S. Department of the Army and GeneOne Life Science, Inc. and conducted at WRAIR. This work was partially supported through a cooperative agreement (W81XWH-07-2-0067) between the Henry M. Jackson Foundation for the Advancement of Military Medicine, Inc., and the U.S. Department of Defense (DoD). GeneOne and the International Vaccine Institute have continued the clinical development efforts on this vaccine as part of a second, Phase 1b/2a trial that is currently ongoing in Korea with the interim data expected later this year. The Wistar Institute also collaborated on the development of this vaccine.
Inovio plans to initiate a larger Phase 2 field trial in the Middle East with through a partnership with CEPI, based on Phase 1b/2a data for INO-4700. Inovio received a $56 million funding last year from CEPI under which Inovio will develop vaccine candidates through Phase 2 against MERS and Lassa fever. The shared goal of Inovio and CEPI is for a MERS vaccine to be available as soon as possible for emergency use as a stockpile post-Phase 2 testing.
Middle East Respiratory Syndrome (MERS) is caused by a coronavirus that is related to the virus which causes severe acute respiratory syndrome (SARS). While the SARS coronavirus infected and caused illness in more than 8,000 people worldwide, the disease was short-lived between 2002 and 2004 and had a case fatality rate of about 10%. Since the MERS was first identified in Saudi Arabia in 2012, as of May 2018 the World Health Organization indicates that laboratory-confirmed MERS cases have been reported for 2,449 people worldwide, with 849 deaths, for a case fatality rate of 35%. Local occasional transmission is still ongoing, primarily in Saudi Arabia where hospital outbreaks occurred earlier this year. Highlighting the global concern for MERS, in the summer of 2015 a single business person returned to South Korea from Saudi Arabia and was the index case for a South Korea epidemic in 17 hospitals around the country. That epidemic was comprised of 186 confirmed cases with a 20% case fatality rate.
